Orbit vs NuanceDeck

Orbit is a spaced-repetition flashcard app built around one idea: memories are satellites, and reviewing them is what keeps them from losing altitude. THE ENGINE Orbit is scheduled by FSRS (Free Spaced Repetition Scheduler) — the same open-source algorithm that's become the standard among serious Anki users because it predicts your memory more accurately than older SM-2-style algorithms. Fewer wasted reviews, fewer forgotten cards. WHAT YOU GET • Anki-style notes and cards, including cloze deletion and rich text (bold, italic, code, fenced blocks) • Image occlusion — turn any photo, diagram, or map into a set of flashcards by drawing masks directly over the parts you want to test yourself on • A full stats suite: retention over time, forecasted review load, a knowledge heatmap, leech detection for cards you keep forgetting, and deadline readiness for exams or deadlines • Streaks, XP, and banked streak freezes that reward consistency without shaming you for a missed day • Text-to-speech playback for hands-free review • A free starter deck — Flags of the World, 197 cards — so there's something worth reviewing the moment you install PRIVATE BY DEFAULT Orbit makes no network calls for your data. Everything — every card, every review, every stat — lives in a local database on your device. Nothing is uploaded, nothing is sold, there are no ads, and there's no account to create. Delete anything, anytime. BUILT FOR DAILY USE Grading a card is a single tap with haptic feedback. The next card is pre-rendered before you finish grading the current one, so review sessions stay fast even for long backlogs. Dark mode is a first-class experience, not an afterthought. Whether you're relearning a language, studying for boards, or just trying to remember more of what you read, Orbit is built to keep it in orbit.

NuanceDeck teaches Russian vocabulary the way you meet it: inside real sentences, with the grammar on the card. EVERY WORD IN CONTEXT More than 7,500 words, each with example sentences. Under every word of a sentence you see its case, the aspect of every verb and the stressed syllable, so you learn the form together with the meaning. Tap any word in any sentence to open its own card. LISTEN, THEN ASK WHY Natural audio for thousands of words and sentences, the most useful ones first. When a sentence puzzles you, ask the built-in AI tutor about that exact sentence, and read the answers other learners already got. DRILL IT IN CONTEXT Conjugation, cases and aspect drills built from real sentences: type the form the sentence needs, pick the right verb, then check the full table on reveal. SCHEDULED BY FSRS Reviews are scheduled by FSRS, the open, research-backed algorithm trained on hundreds of millions of real reviews, so words come back right before you forget them. Your dashboard shows what is due today, your retention, your streak and the shape of your memory. MADE FOR SERIOUS LEARNERS Words are ordered by usefulness and graded by level, from A1 to C1. Browse decks by theme (verbs of motion, greetings, family, food, emotions and more), give a topic priority, and star any word to learn it next.
